ATTORNEYS United States Patent 3,082,593 COMPGSITE TEXTILE YARN Johnathan L. Rhyme, Lincolnton, N.C., assignor of fifty percent to Charles T. Stowe, In, Beimont, N.C. Filed Mar. 13, 1961, Ser- No. 95,171 6 Claims. ((31. 57-139) The present invention relates to textile yarns and more particularly to spun or twisted composite textile yarns wherein sectional portions thereof have predetermined characteristics and the remaining sectional portions have different characteristics.

Broadly considered, the present invention contemplates the provision of a composite textile yarn preferably produced by a spinning, twisting or combined spinning and twisting operation, in which sectional lengths thereof are formed of fibrous strands having predetermined characteristics and other sectional lengths thereof are formed of fibrous strands having different characteristics. A yarn of this character may be used as the warp or filling or both for a woven fabric or as the yarn for a knitted fabric. By suitably choosing the different characteristics of the fibrous strands, a fabric may be produced which has a mottled or variable appearance either to the eye or the hand or both. More specifically, fibrous strands having the characteristics of rough cover or hand may be positioned in a predetermined manner with fibrous strands having the characteristics of smooth cover or hand which would produce a composite yarn having sectional lengths thereof of different cover or hand characteristics. When made into a fabric, such a yarn would impart thereto a variable cover or hand. Still further, fibrous strands of different dye atfinities could be used to produce a yarn of the instant type such that when the yarn or fabric produce-d therefrom is dyed, a mottled effect is produced.

he different characteristics of the fibrous strands may be the natural characteristics of the material or materials of which the fibrous strands are constructed or may be induced characteristics. For example, natural characteristics would include dye afiinity, coarseness or fineness of fibers which would result in rough or smooth cover or hand, and light refiectibility. Induced characteristics would include color which is imparted to the fibrous strmds before inclusion in the yarn, and size or length or both of the sectional lengths of the different fibrous strands.

It is therefore an object of the present invention to provide a novel composite textile yarn and method of manufacturing the same wherein sectional lengths thereof are formed of fibrous strands having one characteristic and other sectional lengths thereof are formed of fibrous strands having at least one other characteristic.

Another object of the present invention is to provide a novel composite textile yarn and method of manufacturing the same wherein a first fibrous strand of predetermined characteristics is fed, drafted and twisted for a predetermined length, a second fibrous strand of different characteristics is fed, drafted and intertwisted in overlapping relation with said first strand, and the feed of the first strand is terminated while the feed, drafting and twisting of the second strand continued.

A further object of the present invention is to provide a novel composite textile yarn and method of manufacturing the same wherein varying lengths of a fibre strand having predetermined characteristics are longitudinally positioned in a predetermined manner with varying lengths of at least one other fibrous strand having ditferent characteristics, the varying lengths of said fibrous strands being overlapped and intertwisted adjacent the terminal portions thereof to form a continuous yarn.

A still further object of the present invention is to Patented Mar. 26, 1963 provide a novel composite textile yarn and method of manufacturing the same wherein a predetermined length of a first fibrous strand of predetermined characteristics is fed to a drafting and twisting mechanism, a second fibrous strand of different characteristics is fed to said drafting and twisting mechanism coextensively with said first strand such that the two fibrous strands are drafted and intertwisted, said coextensive fee-ding, drafting and twisting continuing only for a suificient distance such that the two fibrous strands are secured together, the feed of the first fibrous strand to the drafting and twisting mechanism is then terminated while the feed of the second fibrous strand is continued for a predetermined distance, and the feeding, drafting and twisting of the two strands, and additional strands if desired, is continued in a predetermined order or manner.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- FIGURE 1 is a schematic view partly in section illustrating a spinning or twisting mechanism which may be used in producing the yarn of the present invention;

FIGURE 2 is an enlarged fragmentary detail taken in the direction of arrows 2-2 in FIGURE 1;

FIGURE 3 is an enlarged fragmentary detail of the yarn of the present invention showing the area of intertwisting of the terminal or proximal portions of two sectional lengths thereof;

FIGURE 4 is an enlarged fragmentary detail similar to that shown in FIGURE 3 wherein the area of intertwisting of the proximal portions of two sectional lengths of the yarn has been drafted to be of the same size as the yarn on either side of the intertwisted portion; and

FIGURE 5 is a diagrammatic view illustrating the yarn of the present invention showing the sectional lengths of the fibrous strands and the areas of interconnection therebetween.

Referring to the drawings and more particularly to the FIGURES '1 and 2, the composite textile yarn of the present invention may be produced on any conventional spinning or twisting mechanism or any conventional textile machinery having an attenuating mechanism in cornbination with a twisting mechanism. The mechanism which is preferably to be used is the conventional spinning frame comprising a set of drafting rolls 10, 11, 12

and a twisting mechanism (not shown).

A first fibrous strand A of predetermined characteristics is fed from a suitable source such as a roving bobbin 13, over a guide member 14 to an eyelet 15 mounted in a suitable bracket 16. A second fibrous strand B of different characteristics is fed from a suitable source such as a roving bobbin 17, over guide member 14 to an eyelet 18 mounted in bracket 16. The strands A and B are delivered from the eyelets 15 and 13 to the rear rolls 10 by a feed mechanism generally indicated at 20. Feed mechanism 20 comprises a pair of driven rolls 21 for strand A and a pair of driven rolls 22 for strand B. A suitable guide 23 is mounted between feed rolls 21 and the rear roll 10 for guiding first strand A from feed rolls 21 to the rear rolls 10. A second guide 24 is positioned between feed rolls 22 and rear rolls 10 for guiding second strand B from the feed rolls to the rear rolls. Guides 23 and 24 are convergingly arranged to direct first strand A and second strand B into drafting rolls 10, 11 and 12 in converging paths of travel such that the two strands come together when fed coextensively and exit from the front rolls 12 in sufficiently close proximity to each other to be intertwisted.

While a feed mechanism of the above described type is shown and described as one way in which the fibrous strands may be delivered to the drafting rolls, it is con te rnplated that any fe'eding' means, including manual wo fibrous rands; it is n emPM 'FlL h t e fi tm n for more than tw'efibious trands maybe gran e without departingfrernthe spirit of the instantfinvention;
